Operation; Using The Controllers - Lydall Affinity User Manual

Operation

Using the Controllers

This chiller comes with two FUJI ELECTRIC 1/16 DIN PYX temperature controllers, one for
each loop. These controllers are programmable microprocessors, which offers many more
features than will need to be mastered at this point. Two additional controllers are also provided
to display the flow for each loop in gallons per minute.
These controllers come pre-programmed according to the Affinity™ model selected. If some of
the controllers' additional features become necessary, call Lydall service (603-539-5005) for
technical assistance or consult the FUJI ELECTRIC Instruction Manual.
To power the controllers without powering the chiller, place the ON/OFF/SET switch in the SET
position. The digital display will light up. The number next to PV is the actual process coolant
temperature. The number next to SV is the Set-Value (desired) temperature. Lights next to
OUT1, OUT2, ALM1, and ALM2 may also appear. A light on next to OUT1 (when the switch is
in the ON position) indicates that the chiller is cooling. Both ALM1 and ALM2 are alarms that
are configured differently for different chillers.
